110° C? Does the recipe states that? Then, do it. It won't only be due the glucose but it will also affect to the YE. Where did you get the recipe from? Are you sure it is the glucose that gets charred? YE-containing media use to get darker after autoclaving and that is in direct relation with the time and temp you autoclave.

Similarly, for fungi, malt extract broth has to be autoclaved only 10 min at 115° C, and believe me, that's important.
